. 3 Claims. 1

This invention relates to window constructions and more particularly to a window construction having a storm window and has for its principal object the provision of an improved construction which will be highly efiicient in use and economical in manufacture.

An object of this invention is to provide a storm window arranged in a manner with respect to the remaining portion of the window construction such as will permit the window section thereof to move into the interior of the room for cleaning and Washing purposes without removal of the storm window from its mounting and without interference with the permanent slidable windows.

A still further object of this invention is to provide, in a window construction, storm Windows, the mountings of which require the minimum amount of carpenter work for installation purposes and which when mounted in place are flush with the frames of the window construction.

A still further object of this invention is the provision of a window construction having a storm window the window sections of which are both hingedly and slidably mounted in the frame, thus permitting either sash to be suspended in a position when eased, and convenient access may be had thereto.

A still further object of this invention is the provision of a storm window which when mounted in place is substantially weatherproof for the intended purpose.

A still further object of my invention will be found to reside in the fact that the window section of the storm window is mounted in place by means which facilitates removal of the storm window section without the use of tools.

Another object of this invention is the provision of a storm window which may be conveniently and expeditiousl associated with the standard window construction and one wherein the sash may be cleaned on both sides Without removal of such sash or any part of the storm window.

A still further object of this invention is the provision of a storm sash that can be installed from the inside of the building by one other than a mechanic skilled in such work. As will be apparent, the removal of the storm sash requires no removal of the frame which is mounted permanently in place as will be more apparent hereinafter.

Other objects will appear hereinafter.

The invention consists in the novel combination and arrangement of parts to be hereinafter described and claimed.

The invention will be best understood b reference to the accompanying drawing showing the preferred form of construction, and in which:

Fig. l is an inside elevational View of m improved window construction;

Fig. 2 is a vertical sectional detail View of the same taken on line 2--2 of Fig. 1;

Fig. 3 is a vertical sectional detail view of the window construction embodied in my invention showing the upper storm sash lowered;

FigJl is a vertical sectional detail view similar to that shown in Fig, 3 but showing the lower storm sash in open position;

Fig. 5 is a sectional detail view taken substantially on line 5-5 of Fig. 1;

Fig. 6 is a sectional detail view similar to Fig. 5 showing the upper storm sash in open position;

Fig. 7 is a fragmentary sectional detail view taken on line l--l of Fig. 8 and Fig. 8 is a fragmentary sectional detail view taken on line 88 of Fig. 1.

The drawing illustrates the preferred form of construction of my invention. The several objects of my invention are preferably accomplished by the following construction.

The usual and standard window construction best known to the builder and carpenter, consists of a head jamb IO, comprising a trim II and an outside head casing 12. This window construction further includes an outside side casing 13, a stool I 4 and an outside sill l5 usually sloped outwardly and downwardly for drainage purpose.

The side jambs I6 provide the usual sash runs l7 and I8 for the window sash l9 and 20, each balanced in the usual manner.

It is with this standard window construction that I associate my storm window 2| now to be described in detail.

This storm window 2| comprises a frame 22. The bottom rail 23 of the frame is tapered to correspond to the slope of the outside sill I5. This frame is securely positioned in the window construction as shown. The manner of securing the same in place may vary but it is desirable that it be such that results in a substantially waterproof enclosure.

Mounted in the frame 22 are upper and lower storm sash 24 and 25. The contacting edges of the sash 24 and 25 and those of the frame 22 are rabbettedto provide substantial seals when the sashes are in place whereby to keep out rain, snow, dust and other foreign matter.

The meeting rails 26 and 21 of the sash 24 and 25 are hinged together by means of hinges 28.

These hinges 28 each comprise a pair of hinge leaves 29 and 30. One hinge leaf carries a pintle 3! which fits in a knuckle 32 provided by the other leaf, whereby to separate the sash. All that is necessary is to move one sash in a lateral direction with respect to the other sash to effect removal of the pintle 3| from theknuckle. This may be done without the use of any tools whatsoever.

On the inner vertical edges 33 of the side members of the frame 22 are provided longitudinally extending grooves 34. The sash stile 35 of each sash 2d and 25 carries a set of slidably mounted latch bolts 36 each comprising a finger plate 31 and a latch head 38. These bolts each have an elongated slot 39 formed therein and are movably secured to the sash by a screw element 40 having its shank projected through the slot 39.

When the sash 2-! and 25 are moved relative to the frame 22 the latch heads 38 of the latch bolts 35 work in the grooves 34. To hold the sash 2.4 and 25 in either the position shown in Figs. 3 and 4, the latch head is projected into a keeper notch 45 formed in the side stile of the frame 22 at a proper place for the stated purpose.

Normally the sash are in the position shown in Fig. 1. To clean the lower sash the ends of the iatch bolts 3% thereof are withdrawn from the grooves 35 and the upper sash moved downwardly until the latch bolts 36 thereof engage in adjacent keeper notches :30. This positions the sash 2t and 25 in a position with respect to sash i9 and 23 in a manner such as will permit the lower storm sasli 25 to be pivoted into the position shown inFig. 4 without interference by the meeting rails of the sash l9 and 23.

To move the upper storm sash 24 in the position shown in Fig. 3 the latch bolts 3 5 thereof are disengaged from the grooves 34 and the lower sash 25 raised to the position shown where the upper sash 24 may be pivoted to the position illustrated in Fig. 4 in which position the sash may be cleaned both inside and outside or repaired as the case may require all without removing the storm sash from the frame or detaching one from the other.

The meeting rails ii of the storm sash are rabbeted for weather insulating purposes.

From the above it is obvious that the several objects of my invention are accomplished by a structure which is simple and inexpensive yet highly eflicient in use.

As seen in the drawing when the storm sash are in closed position the meeting rails thereof are directly opposite the meeting rails of the slidable sash l9 and 29. Thus it is apparent that no part of the storm sash when in this position will obstruct any area of the sash l9 and it, a factor w ich is of importance in window construction.

From the description herein set forth it is apparent that a window screen may be used in any well known manner with no interference to the operation or installation of the storm sash.

While I have illustrated and described the preferredform of construction for carrying my invention into effect, this is capable of variation and modification without departing from the spirit of the invention. 1, therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.

Having thus described my invention, what I claim as new and desire to protect by Letters Patent is:

l. A window construction comprising a frame, a pair of aligned sash members arranged in said frame, means for mounting said sash members in said frame for vertical slidable movement with respect to the frame, means connecting said sash members together for swinging movement with respect to each other whereby either of said sash members may be swung from a vertical position in said frame, and means for releasably latching said sash members against slidable movement relative to the frame when one of said sash members is swung from said position within said frame.

A storm window for a window construction having a pair of vertically arranged slidable sash elements, said storm window comprising a frame mounted in said window construction, an upper and lower sash member mounted in aligned relation with respect to each other in said frame, means for mounting said sash members in said frame for vertical slidable movement, means connecting said sash members together for swinging movement with respect to each other whereby when the lower of said sash members is in vertical position within said frame, the upper of said sash members may be swung over the sash elements of said window construction when said sash elements are both in a lowered position with respect to said window construction and whereby when the upper of said sash members is in a vertical position within said frame the lower of said sash members may be swung beneath the said sash elements of said window construction when said sash elements are both in an upper position with respect to said window construction, means for releasably latching said lower of the sash members in said vertical position with respect to the frame when said upper sash member is swung relative thereto, and means for releasably latching the upper of said sash members in its vertical position with respect to said frame when the lower of said sash members is swung relative thereto.

3. A storm window comprising a frame having vertical grooves formed in the opposing edges of the side members of said frame with the grooves extending the full length of said opposing edges and keeper notches communicating with said grooves and formed in said side members, a pair of vertically aligned sash members arranged in said frame, means connecting said sash members together for swinging movement with respect to each other, latch members carried by said sash members and engaging said grooves for guiding said sash members in vertical slidable movement with respect to said frame, when one of said sash members is swung from a vertical position with respect to said frame, the latch members of said other of the sash members being adapted to engage in certain of the keeper notches to releasably latch said other of the sash members against slidable movement within said frame while said one of said sash members is swung from vertical position with respect to said frame.
